Abstract
A radio communication system (100) has a subscriber unit (150) that operates to reduce registration requirements, particularly for power up operations. The subscriber unit (150) saves communication environment information before powering down, and restores the stored communication environment upon a subsequent power up, if the stored environment is deemed current (200, 300). Preferably, the subscriber unit (150) provides notification to the system of its powered up / down status (230, 335). The subscriber unit may complete a full power up registration process if the stored communication environment is determined to be outdated (360).
